bcoz there is decimal next to 2 numbers
You did not provide a list of expressions to select from.
Let A = area
Let w = width
Let (w + 5) = length
A = (w + 5)w
The sample space is {(1,H), (1,T), (2,H), (2,T), (3,H), (3,T), (4,H), (4,T), (5,H), (5,T), (6,H), (6,T)}
On the number cube, she could roll any of the numbers from 1 to 6. On the coin, she could flip heads or tails.
The answer would be 15 +20x. You have to combine like terms.
2+6+7+20x
8+7+20x
= 15+ 20x (answer)
